COFFEE-INFUSEB.

Specification of Letter: Patent.

Patented Feb. 22, v191e.

Application tiled November 2, 1914. Serial No. 869,771.

To all whom t-may concern:

Be it known that I, ISAAC D. RICrrHEIMER, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and .useful Improvements inCo'ee-Infusers, of which the followin is a specication.

My invention re ates to a device for preparing infusions of coffee.

Infusion devices have heretofore been known but have been subject to aserious disadvantage in that it has been necessary in order to get theproper infusionto fill the coffee chamber completely with the coffee forthe reason that the coffee will oat in the water and allow the water to(pass too readily therethrough unless confine A Itis an object of myinvention to provide an infusion device which is capable of use withvarying amounts of coffee depending on the quantity and strength of theliquid desired.

Other ob'ects and advantages of my invention wil be apparent as the sameis better understood by reference to the following specification inconnection with the accompanying drawing n whichspreader 5 is removablydisposed, being nor-` mally held in place by indentations or lugs Figure1 is a vertical section through my improved coffee infusing device, andFig. 2 is a plan view of the same with the cover removed.

Referring to the drawing, 1 indicates a receptacle which may be ofvarying form, the form indicated beingmerely that preferred by me.The/receptacle may be of aluminium or'other suitable material. The lowerportion of the receptacle is preferably reduced inl size in order thatit may be readily inserted in a suitable receiving vessel and isprovided with a perforated bottom 2 over which a filter paper 3 ofspecial composition is adapted to be placed, when the infuser is in use,to support the coffee and prevent it from passing through theperforations. A cover 4 is provided for the receptacle 1. Within thereceptacle 1 a perforated water- 64in the walls of Athe receptacle.Corresponding notches 7 are provided in the water-spreader 5 so'that thewater-spreader may be disposed beneath the lugs 6 and on beingl turnedwill be temporarily locked within -the receptacle 1. A guide 8 isdisposed upon and secured to the waterspreader 5 and slots or othersuitable openings 9 and 10, respectively, are provided in the guide 8and the water-spreader 5. The openings 9 and 10 are adapted to receive astandard 11 at the lower end of which a perforatedplate 12 is secured.The plate 12 is adapted to rest lightly on the coffee which is disposed'above the filter paper 3 and prevent the coffee from floating in thewater as the receptacle 1 is lled. It will be readily understood thatthe plate 12 is adjustable to any height up to the full capacity of thelower portion of the receptacle 1 below the water-spreader 5 and thatthe plate 12 will hold the coieewith suiiicient compactness to preventfloating of the particles in the water while allowing the water topercolate through the coilee and the lter paper 3. A plurality of lugsor indentations 13 are provided in the walls of the lower portion of thereceptacle 1 and corresponding notches 14 are provided in the plate 12,whereby the Slate 12 may betemporarily locked in the esired position.The indentations 13 are preferably alined with the indentations 6 sothat the plate 12 and the water-spreader 5 may be simultaneouslyinserted.

In practice the charge -of coffee is placed lin the receptacle, theplate and water spreader are placed therein, then the receptacle ismounted on the .coi'ee or other receiving means and a sufiicientquantityof boiling water is poured into the receptacle above the water spreader.The water. slowly percolates down through the coffee .and produces aclear and superior coiee` infusion.

A large or small quantity of the coffee in-I fusion may be prepared witheoual facility by varying the charge of coffee and the amount of wateradded.

It will be apparent that various changes may be made in the form,construction and arrangement of the parts without departing from thespirit and scope of the invention or upon the charge of coiee andprevent it from floating in the water, and means for temporarily lockingsaid spreading means and said slldably mounted means within saidreceptacle.

2. In a coee inusing device theeombination of a receptacle, having alower portion of reduced size whereby it is adapted to be inserted in asuitable receiving means, the reduced portion forming a shoulder, a,

'perforated bottom at the extremity of said reduced portion adapted tosupport a 'charge of coffee, a perforated plate for spreading the Water.as itis supplied to said rece tacle, adapted to be supported by saidshouder, a 15 guide mounted on said spreader plate, a standard slidablymounted in said guide and spreader plate, and a perforated plate carnedby said standard and adapted to rest on the charge of coi'ee and preventit from 20 floating in the Watan ISAAC D. v RICI-IHEIMER.`
